What is the volume in liters of hydrogen gas that would be produced by the reaction of 40.0 g of Al with excess HCl at STP accor
DaniilM [7]

The volume in liters of Hydrogen gas = 49.28 L

<h3>Further explanation </h3>

The reaction equation is the chemical formula of reagents and product substances  

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products  

Reaction

2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)

mol Al :

\tt mol=\dfrac{mass}{Ar}=\dfrac{40}{27}=1.481

mol  H₂ :

\tt \dfrac{3}{2}\times 1.481=2.2

At STP, 1 mol =22.4 L

so the volume of hydrogen :

\tt 2.2 \times 22.4=49.28~L
